I have had a Sony prs-505 that I have given away to my wife after buying a PocketBook 360.

The PB360 is really good with allot of formats and many many features.
But these all features comes at a price: the basic ones for reading borrowed epub's is not working so well in the current version of the firmware, and I don't have so big hope for improvements especially regarding that the main format for the Ukrainian software is there own FB2 format.

Then I hoped for the Opus from Bookeen, but from the answers I have got so far in the Bookeen forum it doesn't seem to work so well either.

I gave my sister a PRS-300 so I tested it a bit before, the software is quite good but I prefer the buttons on the sides (both or on one side + the possibility to rotate) so it is possible to read with either left or right hand.

The EZ Reader Pocket Pro (Hanlin V5) is a good choice for Adobe lending library ebooks. It is a bit more expensive than the PRS-300, but has more capabilities and in particular has three ways to turn pages (left center keys, bottom right keys, and right top scroll wheel). It is also currently on sale, see Mother's Day Blowout on all EZ Readers.

Thank you wallcraft for answering!

Does it show how many days are left like the sony's and/or does it show expire date in some info page?

How many zoom-levels/fonts-sizes can be used for borrowed epub's?

Do you use both left-hand and right-hand reading?

I was using a Hanlin v3 for a little while but it was really slow, what about the speed to turn pages?

Is epub the major format? that has the most features and most stable ones also?

I hear you can extend the time of borrowing a book by not connecting it to the pc once the book is open and by charging it through the mains. Is that correct

No I don't think so.

I even heard that on the "Letto" a Swedish re-branded Bebook One, the Adobe Digital edition implemented on the device had its own "Real-time-clock".
So even if you tried to set back the date, the borrowed epub expired at correct date. I haven't tried this on any reader, but it seems reasonable.

No, it just locks itself. In this, I haven't checked with PB360 or BeBook Mini, but I can guarantee for Sony models (so I suppose the PRS300 too). I'd vote for the Mini just because sometimes there's a bit of, er, conflict between ADE (which is the "proper" software for libraries) and Sony EBL (which used to keep the book anyway, even if it's locked- ILLOGICAL).

This way of reading past the due date is working fine on my Sony PRS-505. I just recently got access to public library (ADE) ebooks, and this is what I did:
- haven't connect to a computer
- charge via A/C adapter/mains
- have kept that ebook open on the Reader
- don't do full shutdown (only use the switch at the top, or auto power off).

I'm not sure if the latter two are required. Sorry, I don't want to chance testing anything until I finish this book.

Just checked, and the library ebook still reads fine. It's about a month past due.
